OVERHEAD TROLLEY.

To all whom it may concern:

Be it known that l, RICHARD A. PncLAn, a subject of the King of GreatBritain, and a resident of Toronto, in the Province of Ontario andDominion of Canada, have invented an Improvement in Overhead .Trolleys,of which the following is a specification.

My invention is an-attachment for overhead trolley poles, the same beingdesigned and adapted to aid in replacing a trolley wheel on theconducting wire when the same has been accidentally displaced. Thetrolley rope is wound on a spring-retracted drum which is automaticallyreleased when the trolley wheel is displaced from the wire, and wherebythe rope is taken up, or wound on the drum, and thus the trolley wheelis drawn down below the wire into position to be easily and quicklyreapplied thereto.

The details of construction, arrangement, and operation of the inventionare as hereinafter described, and illustrated in the ac companyingdrawings, in which Figure 1 is mainly a side view of a trolley poleprovided with my improvement, the attachment thereto being shown in thenormal position. Fig. 2 is a similar view, save that the attachment isshown in the position occupied when the trolley wheel has left the wire.Fig. 3 is a plan view of a trolley pole provided with the attachment.Fig. 4t is an enlarged cross section on the line a e of Fig. 3. Fig. 5is an edge view of the trip arms.

A trolley pole 1 carrying a grooved wheel 2, adapted to run in contactwith a conductor 0c, is pivoted at 3 and provided with a supportingspring t in the usual way. The trolley rope 5 runs over a pulley 6suspended from a bracket 7 attached to the pole 1, adjacent to the wheel2, and extends back from such pulley and is attached to a short bar 8which, as shown in Fig. 3, is arranged transversely beneath the pole andsupported upon a hook 9 extending down ward parallel to the pole. Thesaid bar 8 is connected by wires or cords 10 with a flanged drum 11which is fixed on one end of a shaft around which a spring 12 is coiledas shown in Fig. 3. The shaft and drum are supported rotatably in abracket 13 which is attached to the under side of the pole 1 and extendstransversely thereof. The spring 12 is so connected with the drum andbracket as to tend to rotate the drum Specification of Letters Patent.

in the direction indicated by arrow in Fig 1, so as to wind the, wires10 thereon.

lVhen tension is applied to the trolley rope 5 for setting the wheel 2011 the wire as, the short bar 8 will be drawn up against the upper endof the hook 9, and, obviously, in such operation, the wires 10 will beunwound from the drum, the spring 12 being wound and put under tensionto a corre sponding degree. into the position indicated see 1-it is heldin place by means of a device in the nature of a latch 14;, the samebeing pivoted to the upper end of the hook 9 and provided with shoulders14;, adapted to engage the bar 8, and with a U-shaped loop 14 whichpasses over the trolley pole. It will be understood that the pivoted endof this latch 14 is duplicated on the opposite side of the pole, so thattwo shoulders 141-. engage the bar 8 when the latch is in the lockingposition shown in Fig. 1. After the parts have been drawn into thisnormal locking posi tion, the tension on the rope 5 being released, thelatch holds the bar 8 against the resistance of the spring-retracteddrum until it shall be automatically released upon the trolley wheelleaving the wire. Such release is effected by the means now to bedescribed. The bracket '2' before referred to is approximately V-shapedand pendent from the trolley pole, and a device 15 in the nature of anelbow lever is pivoted to said bracket and its shorter arm is connectedby wires 16 with the arms of the latch 14-. The trip lever 15 isprovided with side guides 15 which embrace opposite sides of the pole 1as shown. A spiral spring 17 is also connected with the latch, as shown,for bold ing it normally in engagement with the sliding bar 8 beforedescribed.

Rods 18-see Fig. 3proiect laterally from the upper free end of thedevice 15, and together these two parts constitute a trip, whichoperates as follows. When the parts are in the normal position, the triplever 15 is supported by a spring 19 in the position shown in Fig. 1,that is to say, in contact with the under side of the trolley. When,however, the wheel 2 accidentally leaves the wire w, the spring 4 willthrow the pole upward into the position shown in Fig. 2, in which caseone of the rods or lateral arms 18 will come in contact with the wireand thereby the trip lever 15 will be thrown down to the position shownin Fig. 2, where- When the bar 8 slides by, through the tension thusapplied by the Wires 16, the latch 14: will be tripped and the short bar8 thereby released, whereupon the spring drum will be rotated to take upthe slack of the trolley rope 5, with the result that the trolley polewill be drawn down automatically to the position indicated by dottedlines in Fig. 2, so that it is in readiness to be quickly and easilyapplied again to the wire. In brief, whenever the trolley leaves thewire, one or the other of the arms 18 must come in contact with thelatter, whereby the latch 14: is automatically tripped by the lever 15and connected wires 16, thereby allowing the spring drum to come intoaction and automatically draw down the trolley pole to a position belowthe wire. The ends of trip arms 18 are inclined downward at an angle ofabout 45, and shoulders are formed at the inner ends of the inclines, asshown in Fig. 5.

What I claim is 1. The combination with a spring-supported trolley pole,of a rotatable spring retracted drum, a trolley rope operativelyconnected with said drum so as to be taken up when the drum is rotatedby its spring, a pivoted latch serving to lock the drum with the springunder tension, and a trip device connected with such latch and pivotedon the outer end of the trolley-pole and having laterally extended armswhich come in contact with the wire when the trolley leaves the same,substantially as described.

2. The combination with a spring-supported trolley-pole, a trolley-ropeand a guide for the latter which is applied to the outer end of thepole, a bar on the lower portion of the pole with which the trolley-ropeis connected, a rotatable spring-retracted drum, :1 pivoted latchadapted to engage such bar, means connecting said bar with the drum, atrip device applied to the upper end of the pole and provided withlateral arms adapted for contact with the wire when the trolley leavesthe same, and means connecting such trip with the latch, whereby theoperation of the trip operates the latch and thereby releases the drumso that it winds up the trolley rope automatically and thus draws thetrolley below the wire, substantially as described.

3. The combination with a spring-supported trolley pole, a trolley rope,and a spring retractor for the same, of a trip device comprising a partpivoted to the outer end of the pole and having lateral arms adapted tocome in contact. with the wire when the wheel leaves the same, and meansconnected with the trip and serving to normally lock the retractor andto automatically release the same when tripped, as shown and described.

t. The combination with a spring-supported trolley pole, a trolley ropeand. a spring actuated rotatable retractor, and means for looking thesame in normal position, of a pivoted swinging trip device applied tothe upper end of the pole and adapted for contact with the wire when thewheel leaves the same and connected with the retractor, whereby it isthrown downward and thus releases the retractor, substantially asdescribed.

5. The combination with a spring-supported trolley pole, a trolley rope,a spring retracted rotatable drum, and a slidable bar to which the ropeis attached, a guide attached beneath the pole upon which the said baris adapted to slide, wires connecting such bar with the drum, a pivotedlatch adapted to engage the bar and hold it normally in position forlocking the retractor, and a trip connected with said latch and appliedto the upper portion of the pole, sub stantially as described.
